Leo’s papacy was marred by his military action. He added new Italian regions to the papal states, and when Normans invaded these areas in 1053, he personally led an army to throw them out. This resulted in wide-spread criticism, defeat in the field, his capture at Civitella, and several months imprisonment at Benevento, Italy. He spent his time there well, learningGreek to better understand the writings of the Eastern Church, but his health suffered badly, and he died soon after his release.
